Embryonic exposure to prothioconazole induces oxidative stress and apoptosis in zebrafish (Danio rerio) early life stage

Triazole fungicides are extensively applied in general agriculture for fungal control and have negative impacts on aquatic organisms. Prothioconazole, a widely used triazole fungicide, is toxic to zebrafish, but systematic research on the negative effects caused by prothioconazole in zebrafish embryos is limited. In this study, we studied the developmental toxicology, oxidative stress and apoptosis caused by prothioconazole in zebrafish embryos. Exposure to 0.850 ma prothioconazole impacts embryo survival and hatching. Prothioconazole exposure caused embryo malformation, especially yolk-sac and pericardial edemas, and prothioconazole-induced apoptosis was observed. Additionally, exposure to a high prothioconazole concentration up-regulated the expression levels of oxidative stress defense-related genes and p53. The bax to bcl2 ratio increased along with exposure time and prothioconazole concentration. Prothioconazole induced apoptosis during the early life stages of zebrafish and may trigger oxidative-stress and p53-dependent pathway responses. Our findings increase our understanding of the molecular mechanisms of oxidative stress and cell death caused by prothioconazole. (C) 2020 Elsevier B.V. All rights reserved.

Efficient synthesis and DFT analysis of novel 1,2,3-triazole-based dithiocarbamates

Novel 1,2,3-triazole-dithiocarbamate hybrids were synthesized in moderate to good yields (60-75%) in green solvent system H2O/t-BuOH by click azide-alkyne [3 + 2] cycloaddition reaction with avoiding isolation and handling of hazardous organic azides. The structure of the all products were unambiguously characterized by various techniques such as CHN, (HNMR)-H-1, (CNMR)-C-13, ESI-MS and FT-IR. The synthesis protocol proceeds under easy, green and mild reaction conditions with available inexpensive starting materials. The HOMO-LUMO analysis (electrophilicity index), H-1 and C-13 chemical shifts and Mulliken charge distribution of the characterized structure of 4a have been also calculated by applying B3LYP/6-31+G (d, p) level of density functional theory (DFT) method.

Flavonoid Glycosides with a Triazole Moiety for Marine Antifouling Applications: Synthesis and Biological Activity Evaluation

Over the last decades, antifouling coatings containing biocidal compounds as active ingredients were used to prevent biofouling, and eco-friendly alternatives are needed. Previous research from our group showed that polymethoxylated chalcones and glycosylated flavones obtained by synthesis displayed antifouling activity with low toxicity. In this work, ten new polymethoxylated flavones and chalcones were synthesized for the first time, including eight with a triazole moiety. Eight known flavones and chalcones were also synthesized and tested in order to construct a quantitative structure-activity relationship (QSAR) model for these compounds. Three different antifouling profiles were found: three compounds (1b, 11a and 11b) exhibited anti-settlement activity against a macrofouling species (Mytilus galloprovincialis), two compounds (6a and 6b) exhibited inhibitory activity against the biofilm-forming marine bacteria Roseobacter litoralis and one compound (7b) exhibited activity against both mussel larvae and microalgae Navicula sp. Hydrogen bonding acceptor ability of the molecule was the most significant descriptor contributing positively to the mussel larvae anti-settlement activity and, in fact, the triazolyl glycosylated chalcone 7b was the most potent compound against this species. The most promising compounds were not toxic to Artemia salina, highlighting the importance of pursuing the development of new synthetic antifouling agents as an ecofriendly and sustainable alternative for the marine industry.

Co(III), Rh(III) & Ir(III)-Catalyzed Direct C-H Alkylation/Alkenylation/Arylation with Carbene Precursors

Metal carbenes play a pivotal role in transition-metal-catalyzed synthetic transfer reactions. The metal carbene is generated either from a diazo compound through facile extrusion of N-2 with a metal catalyst or in situ generated from other sources like triazoles, pyriodotriazoles, sulfoxonium ylides and iodonium-ylide. On the other hand, Co(III), Rh(III) & Ir(III)-catalyzed C-H functionalizations have been well established as a key synthetic step to enable the construction of various synthetic transformations. Interestingly, in recent years, merging of these two concepts C-H activation and carbene migratory insertion gained much attention, in particular group 9 metal-catalyzed arene C-H functionalizations with carbene precursors via carbene migratory insertion. In this review, we summarize recent advances in Co(III), Rh(III) & Ir(III)-catalyzed direct C-H alkylation/alkenylation/arylation with carbene precursors and also discuss key synthetic intermediates within the catalytic cycles.

Water Soluble Iron-Based Coordination Trimers as Synergistic Adjuvants for Pancreatic Cancer

Pancreatic cancer is a usually fatal disease that needs innovative therapeutic approaches since the current treatments are poorly effective. In this study, based on cell lines, triazole-based coordination trimers made with soluble Fe(II) in an aqueous media were explored for the first time as adjuvant agents for the treatment of this condition. These coordination complexes were effective at relatively high concentrations and led to an increase in reactive oxygen species (ROS) in two pancreatic cancer cell lines, PANC-1 and BXPC-3, and this effect was accompanied by a significant reduction in cell viability in the presence of gemcitabine (GEM). Importantly, the tested compounds enhanced the effect of GEM, an approved drug for pancreatic cancer, through apoptosis induction and downregulation of the mTOR pathway. Although further evaluation in animal-based models of pancreatic cancer is needed, these results open novel avenues for exploring these iron-based materials in biomedicine in general and in pancreatic cancer treatment.

Synthesis of 1-aroyl-3-methylsulfanyl-5-amino-1,2,4-triazoles and their analysis by spectroscopy, X-ray crystallography and theoretical calculations

N-Aroyl-1,2,4-triazoles TAM and TACl were regioselectively synthesized in excellent yields through an efficient N-acylation reaction of 3-amino-5-methylsulfanyl-1H-1,2,4-triazole with aroyl chlorides. Structures of N-aroyl-1,2,4-triazoles were studied by single-crystal X-ray diffraction, observing that their crystal structures are characterized by the formation of dimers through N-H center dot center dot center dot N bonds. The supramolecular assembly depends on the sort of connections between dimers, which notably change with the parasubstituent on the aroyl group. The directly calculated ionization potential (IP), electron affinity (EA), electronegativity (chi), electrophilicity index (omega), hardness (eta), and chemical potential (mu) are correlated with the HOMO and LUMO orbital energies. Moreover, molecular electrostatic potential maps of both molecules have been calculated showing a negative region at N2 atom of the 1,2,4-triazole ring instead of exocyclic amino group. The vibrational spectral analysis was carried out using infrared spectroscopy in the range 4000-400 cm(-1) for N-aroyl-1,2,4-triazoles TAM and TACl. The experimental spectra were recorded in the solid state. The fundamental vibrational frequencies and intensity of vibrational bands were evaluated using density functional theory (DFT) with the standard B3LYP/6-31G(d,p) method and basis set yielding fairly good agreement between observed and calculated frequencies. Simulation of infrared spectra utilizing the results of these calculations led to an excellent overall agreement with the observed spectral patterns. (C) 2020 Published by Elsevier B.V.

Thermodynamics of transfer and partition of 3,5-diamino-1-phenyl-1,2,4-triazole in the 1-octanol/water biphasic system

In this paper, we focus for the first time on thermodynamics of transfer of 3,5-diamino-1-phenyl-1,2,4-triazole (DAPT) from water to liquid 1-octanol which is considered in pharmaceutical chemistry as an appropriate model of a lipid-like environment for studying a passive membrane transport of various drugs. The enthalpies of solution of DAPT have been determined calorimetrically in both solvents at 298.15, 308.15 and 328.15 K. The partition coefficients (P) have been obtained in the 1-octanol/water biphasic system at 298.15 and 328.15 K using a classical isothermic saturation method. Standard thermodynamic functions of DAPT transfer from water to a lipid-like phase have been calculated via the Gibbs-Helmholtz equation using the temperature dependence of the standard enthalpies of solution and the partition coefficient at the reference temperature of 298.15 K. We have found that the enthalpic term favours the solute transfer both at lower and elevated temperatures, whereas the entropic one contributes in the opposite manner. The free energy of transfer remains negative for all the temperature range studied indicating rather appreciable affinity of a potential drug towards a lipid-like environment. The comparison of the experimental and calculated P values indicates that our approach is able to predict with a good accuracy the behaviour of the 1,2,4-triazole derivatives for the physiological temperature range.

Identification and Characterization of Mortaparib(Plus)-A Novel Triazole Derivative That Targets Mortalin-p53 Interaction and Inhibits Cancer-Cell Proliferation by Wild-Type p53-Dependent and -Independent Mechanisms

Simple Summary Functional inactivation of tumour suppressor protein p53 is frequently found in a large variety of cancers. One of the mechanisms by which p53 is inactivated is through its interaction with mortalin protein that inhibits its translocation, and hence the function, in the nucleus. Abrogation of mortalin-p53 interaction has been suggested as a target for cancer therapy. We report here a novel multimodal small molecule, called Mortaparib(Plus), that causes growth arrest or apoptosis of cancer cells by abrogating mortalin-p53 interaction yielding reactivation of p53 function. It also causes upregulation of tumour suppressor protein p73, and inactivation of PARP1 and CARF proteins accounting for its multimodal anticancer activity. p53 has an essential role in suppressing the carcinogenesis process by inducing cell cycle arrest/apoptosis/senescence. Mortalin/GRP75 is a member of the Hsp70 protein family that binds to p53 causing its sequestration in the cell cytoplasm. Hence, p53 cannot translocate to the nucleus to execute its canonical tumour suppression function as a transcription factor. Abrogation of mortalin-p53 interaction and subsequent reactivation of p53’s tumour suppression function has been anticipated as a possible approach in developing a novel cancer therapeutic drug candidate. A chemical library was screened in a high-content screening system to identify potential mortalin-p53 interaction disruptors. By four rounds of visual assays for mortalin and p53, we identified a novel synthetic small-molecule triazole derivative (4-[(1E)-2-(2-phenylindol-3-yl)-1-azavinyl]-1,2,4-triazole, henceforth named Mortaparib(Plus)). Its activities were validated using multiple bioinformatics and experimental approaches in colorectal cancer cells possessing either wild-type (HCT116) or mutant (DLD-1) p53. Bioinformatics and computational analyses predicted the ability of Mortaparib(Plus) to competitively prevent the interaction of mortalin with p53 as it interacted with the p53 binding site of mortalin. Immunoprecipitation analyses demonstrated the abrogation of mortalin-p53 complex formation in Mortaparib(Plus)-treated cells that showed growth arrest and apoptosis mediated by activation of p21(WAF1), or BAX and PUMA signalling, respectively. Furthermore, we demonstrate that Mortaparib(Plus)-induced cytotoxicity to cancer cells is mediated by multiple mechanisms that included the inhibition of PARP1, up-regulation of p73, and also the down-regulation of mortalin and CARF proteins that play critical roles in carcinogenesis. Mortaparib(Plus) is a novel multimodal candidate anticancer drug that warrants further experimental and clinical attention.

Tebuconazole exposure disrupts placental function and causes fetal low birth weight in rats

Tebuconazole (TEB) is one of the widely used broad-spectrum triazole fungicides. Its accumulation in mammals leads to various endocrine disruptions. However, it is unclear whether the exposure of TEB during pregnancy affects the growth and development of fetus and placenta. Here, TEB was exposed to pregnant Sprague-Dawley female rats from gestational days 12-21 of 0, 25, 50 or 100 mg/kg for 10 days. TEB reduced placental estradiol levels. TEB disrupted the structure and function of the placenta, leading to hypertrophy, fibrin exudation, edema, calcification, arterial fibroblast proliferation, and trophoblastic infarction. RNA-seq analysis showed that TEB mainly down-regulated the expression of iron transport genes and up-regulated the expression of genes for immune/inflammatory responses. Further qPCR showed that TEB down-regulated Tfrc, Hamp, Elf 2ak2 and up-regulated the expression of Cd34, Cd36, Jag1, Pln, Cyp1a1, Esrra, and Aqp1 at 50 and 100 mg/kg. Western blot and semi-quantitative immunohistochemical staining also demonstrated that TEB lowered the levels of TFRC and EIF2AK2 and increased the levels of CD34, CD36, JAG1, CYP1A1, and ESRRA at 50 and 100 mg/kg. In conclusion, TEB severely damages the structure and function of the placenta, leading to hypertrophy of the placenta, low birth weight and feminization of the male fetus possibly via several pathways including iron transport and THE signaling.
